Example of an incorrectly identified `InconsistentlySynchronizedField` warning in ReSharper

sync.cs

using System;

public class Foo {
    private int[] _arr;
    private readonly Guid _id;
    private readonly object _lockObj;
    
    public this[int index] {
        get => _arr[index];
        set => Set(index, value);
    }

    public Foo(Guid id) {
        _id = id;
        _lockObj = new object();
    }

    private void Set(int index, int val) {
        lock (_lockObj) {
            // this is throwing InconsistentlySynchronizedField, because it's
            // part of a locked context, not because there is an actual
            // synchronization issue.
            Console.WriteLine($"Guid is {_id.ToString()}");
            _arr[index] = value;
        }
    }
}
